-Both minerals have identical physical properties.
-Mineral A is made from different elements than Mineral B.
-Mineral B is a gem, but Mineral A is a common mineral.
Answer:
The correct answer is "Both minerals have the same true color".
Explanation:
A mineral color streak refers to the color the mineral displays when is in a finely powdered form. Even though the color streak could be completely different from the one the mineral displays when is as a hand specimen, it is considered that the true color of the mineral is the color streak. Therefore, maybe mineral A and mineral B are purple and black when they are as hand specimen, respectively. But if both minerals leave the same color streak, both minerals have the same true color.
Answer: Mineral A is made from different elements than Mineral B.
Explanation:
A mineral is an inorganic substance obtain from below the earth crust in the geospheres. They are obtain from the rocks by mining process. These minerals can be identified by their physical and chemical properties. The physical properties include color of the mineral. The color of the mineral can be observed externally but two or more minerals may have the same color externally. But by using the streak method the mineral is rubbed over a surface. The color of the powder obtained after this process is the exact color of the mineral which can be used to distinguish between two minerals. It defines the elemental composition of the mineral.

Lesson 2: Energy Roles of Organisms
Explanation:
1. B. They both produce carbohydrates
2. B. They both obtain energy by consuming other organisms.
3. C. Carnivore, Consumer
4. A. A decomposer breaks down organic compounds in dead organic matter, and a detritivote eats dead and decaying mater.
B. Mutations.
C. Nonrandom mating.
D. No immigration or emigration.
Answer:
The correct answer would be D. No immigration or emigration.
It can be explained with the help of Hardy-Weinberg law.
It states that the genotype and allelic frequency of the population remains the same throughout many generations if below-mentioned conditions are followed:
Nonrandom mating is one of the conditions required to maintain genetic equilibrium.
One of the conditions required to maintain genetic equilibrium is nonrandom mating. Nonrandom mating occurs when individuals preferentially choose mates with particular traits, rather than mating randomly. This can lead to changes in the frequency of traits within a population over time.

b. False
The correct answer is; b. False
A hormone is not an organ. Hormones are chemical substances that are produced in the endocrine glands in the body. Hormones act as special messengers by controlling almost all bodily functions such as hunger, reproduction, emotions and mood. Examples of hormones and their major function are insulin (metabolic hormone), estrogen (sex hormone), adrenalin (stress hormone), ghrelin (hunger hormone), leptin (satiety hormone), melatonin (sleep hormone), testosterone (sex hormone) and thyroid (growth hormone).
Answer:
The answer is B.
Explanation:
A hormone is a chemical substance produced and released by endocrine glands to help regulate bodily functions.

Which of the statements below is true about the alleles for eye color in fruit flies?
A)
The alleles for eye color produce the same phenotype.
B)
The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.
C)
Changes in the sequence of DNA bases in a gene do not contribute to genetic variation in the fruit fly population
Answer:
The correct answer would be B) The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.
The amino acid sequence of any protein is determined by the codon sequence of the mRNA which is in turn determined by the nucleotide sequence of the DNA.
Thus, if the nucleotide sequence of the DNA is changed, it will result in the change of amino acid sequence of the protein.
It may result in the change of the structure as well as the function of the protein.
Thus, if the sequence in the gene is changed slightly, it would not result in the production of protein required for a red color trait.
Hence, the eye color of the fruit fly would change to white.
